RECONCILIATION PROTOCOL AFTER ICR SWITCHOVER DURING BULK SYNC

摘要

According to one embodiment, a method for performing reconciliation sync includes a first network device configured as an active inter-chassis redundancy (ICR) device in response to detecting a switchover request while performing a bulk sync transitioning to serving as the standby ICR device and performing a reconciliation sync while serving as the standby ICR device, the reconciliation sync comprises starting a transmission of session records that failed to be transmitted during the bulk sync to the second network device.;According to one embodiment, a method for performing reconciliation sync includes a first network device configured as a standby ICR device receiving a plurality of session records from a second network device of the ICR system. The method further includes updating a global version number based on record version numbers of the received plurality of session records, and maintaining local session records based on the received plurality of session records.

1. A method in a first network device of an inter-chassis redundancy (ICR) system that is communicatively coupled to a second network device of the ICR system, the first network device configured as an active ICR device of the ICR system, the second network device configured as a standby ICR device of the ICR system, the method comprising:
performing a bulk sync in response to detecting the second network device is configured as the standby ICR device, wherein the bulk sync comprises starting a transmission of all session records maintained at the first network device of the ICR system to the second network device of the ICR system; and in response to detecting a switchover request while performing the bulk sync:
transitioning to serving as the standby ICR device of the ICR system, andperforming a reconciliation sync while serving as the standby ICR device, wherein the reconciliation sync comprises starting a transmission of all remaining session records that failed to be transmitted during the bulk sync to the second network device of the ICR system.
